tabby cat in my backyard is it yours

Hello, there is a dark or mackerel tabby cat small to medium size sitting under a bush in my back yard. It has its head down as if trying to sleep, does not seem injured. Not wearing a collar and fur coat looks nice. I am at Bryant and Negley. If you are missing your cat please respond ASAP.I cannot take it in to my house as my cat does not tolerate other animals and I can't risk this kitty having FeLV. If it is still there in the AM I may call Animal Control. Nanci .....
